Letters Patent No. 94,190, dated August 31, 1869.

IMPROVEMENT IN PUMPS.

The Schedule Areferred to in these Letters Patent and making part of the same.

To all whom z'tmay concern:

Be it known that I, ALEXANDER Dixon, of Aurora, in the county of Kane, and State of Illinois, have nvented a new and useful Improvement in Double-Acting Water-Engines; and'I do declare that the following is a true and accuiate description thereof, reference being had to the accompanying drawings, and to theV letters of reference marked thereon, and being'a part of this specification. A

` The nature of this invention relates to an improved construction of a double-acting lifting and direc-pump,

vA represents two cylinders, securely fastened, at

suitable distances apart, on the bed-plate or frame B.

These cylinders are provided with proper stalling- 4boxes a ,through which the piston-rod passes. They are also provided with side pipes b, leading from each head of each cylinder to the valve-chambers C, within which are placed suitable inlet and outlet-valves.'

These valve-chambers are connected attheir bottoms to the suction-pipe D,'and. at their tops to the Adischarge-pipe E, which is provided with va proper airchamber, F.

The piston-rod c, sustained in its reciprocating motion in bearings d, is provided with a rack, e, Iigidly secured to said rod, which engageswith a segmentaltoothed or eoggedA wheel, f, which is operated'and semi-rotated by means of suitable handles inserted into sockets G, secured to the hub g, which is jonr-l nalled at h for thatpurpose. l

To operate this device, attach a suitable suctionhose to the connection H, and drop its opposite end into water. A proper hose or pipe should be also attached to the open end of the discharge-pipe, at I. Then, by alternately working the levers -or handles whichare inserted into the sockets G, backward and forward, a reciprocating motion is given to the piston-v rod by means of the segmental pinion and rack, when the cylinders are alternately .lilled and discharged by the proper action of suitable valves in the valve-chambers, so that there is a constant stream of water discharged froux the pipe.

What I claim as inyinvention, and desire to secure by Letters Patent, isY

The peculiar arrangement of the two cylinders A, bedplate '15, stufng-boxes a, side pipes b, valve-chambers C, suction-pipe D, discharge-pipe E, air-cha1nber F, piston-rod c, bearings d, rack e, segmental-cogged wheel f, sockets G, and hub g, or their equivalents,

when constructed, combined, and operating, substantially as and for the pnrposesherein described. l'
